Abstract

During a short duration injection, a triangular geometry is drawn in terms of the injection rate with respect to time, while a trapezoidal geometry is drawn during a long duration injection. The ON timing of the drive pulse is determined to be at a valve opening pressure achieving time (Tds) before the start point of formation in time (a1) of the geometry. An injection pulse duration (Tqf) is determined from "the valve opening pressure achieving time (Tds) + a needle rise time (Tqr) - a valve closing pressure achieving time (Tde1)," and then the OFF timing of the drive pulse is determined.
